CHARLES LUND, OF CHEBOYGAN, MICHIGAN.

BUMPER FOE AUTOMOBILES.

Application filed August 5, 1924. Serial No. 730,259.

T 0 all whom it may concern:

Be it known that 1, CHARLES LUND, a citizen of the United States, residing at Cheboygan. in the county of Cheboygan and State of Michigan, have invented a new and useful Bumper for Automobiles, of which the following is aspecification.

This invention relates to bumpers for automobiles and the object thereof is to provide a device of this character which combines attractiveness with substantiability and which will absorb the shocks of ordinary blows or bumps.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of a bumper constructed in accordance with this invention;

Fig. 2 is a top plan View thereof;

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2; and

Fig. 4 is a similar view taken on the line 4-4; of Fig. 2.

In the embodiment illustrated two metal strips 1 and 2 are spaced laterally apart being designed to extend transversely of the vehicle and are connected by longitudinally spaced plates 5, any desired number of which may be employed which may be of any desired configuration being here shown substantially oval in shape and riveted or otherwise secured to the strips 1 and 2 as is shown clearly in Fig. 1. The ends of these strips 1 and 2 are equipped with knuckles 4; and 5 through which extend connecting pintles 6 which connect the strips 1 and 2 with each other and with the outer ends of springs 7 and 8 which are arranged opposite the space between the members 1 and 2 and are equipped at said outer ends with knuckles 9 designed to be arranged between the knuckles L and 5 of the strips on the pintles 6 as is shown clearly in Fig. 3.

The springs 7 and 8 are in the form of leaf springs attached to the bumper members 1 and 2 as above described and which 1 have their inner ends lapping as shown at 10 and held slidable relatively to each other by a clip 11 which is riveted or otherwise secured to the strips 1 and 2 and to one of the plates 3 as is shown clearly in Fig. l,

The springs 7 and 8 are constructed exactly alike having inwardly bowed outer and inner ends as shown at 12 and 13, said ends being connected by a straight portion or arm 14 which portions 14 are equipped with brackets 15 of any suitable or desired construction for connecting the bumper to the car.

The connection of the inner ends of the springs 7 and 8 by the clip 11 which permits them to slide longitudinally provides for the expansion of the springs when a blow is received on the plate 3, the recoil of the spring causing them to slide inwardly on each other and assume initial position after being hit. The center of the spring is fastened rigidly to the frame and consequently mustresume their initial position after being forced to slide on each other since this spring is tempered.

The outer faces of the plates 3 and of the strips 1 and 2 are preferably nickel plated or otherwise ornamentally finished to add to the attractiveness of the bumper.

I claim 1. A deviceof the class described comprising an outer blow receiving member having knuckles at its ends leaf springs having cooperating knuckles which are pivotally connected with the outer member, the inner ends of said springs being arranged in lapping relation to slide longitudinally relatively to each other, and a clip carried by the outer member in which said ends slide.

2. A bumper of the class described comprising two parallel laterally spaced strips arranged in edgewise alinement, spaced plates connecting said strips, and leaf springs connected at their outer ends with the ends of said strips and having their inner ends slidable relatively to each other and a guide carried by said outer strips in which said ends slide.

8. A device of the class described comprising laterally spaced edgewise disposed alined strips having knuckles at their ends,

leaf springs having knuckles at their outer ends adapted to be arranged between the knuckles of-the strip ends, pintles connecting said knuckles a clip carried by the inner 5 faces of said strips, the inner ends of said springs being slidably mounted iIiSEtiCi clip.

In testimony that] claim the fereging as I my own, I have hereto afiixed my signature in the presence of two Witnesses.

I CHARLES" LUND.
